GAS-STOVE.

SPECIFICATION forming partof Letters Patent No. 771,955, dated October11, 1304. Application filed November 2 1903. Serial No. 179,527. (Nomodel.)

To all whom it may concern:

Be it known that LLEwIs O. WA'rsoN, a citi zen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Gas-Stoves, of which the following is aspecification containing a full, clear, and exact description, referencebeinghad to the accompanying drawings, forming a part hereof.

My invention relates to improvements in gas-stoves, and has for itsobject to effect the conservation of the heat developed by the burnersemployed at the top of a gas-stove.

My improved gas-stove comprises an imperforate bottom, imperforate wallsextending upwardly around the edge of said bottom and forming aheat-chamber, partition-walls dividing said heatchamber into heat com- Ipartment of the series.

In the drawings, Figure 1 is a perspective view of the upper portion ofa gas-stove embodying my invention.- Fig. 2 is a perspec tive view ofthe upper portion of a gas-stove embodying my invention, showingportions of the outer walls broken away.

My invention is intended for use'in gasstoves having two or more holes.

Heretofore gas-stoves have been constructed having open tops with anumber of burners arranged therein, such burners being adapted to heatvessels immediately above them, no provision being made to utilize thesurplus heat by lateral distribution.

It is the primary object of my invention to provide a gas-stove having asolid top and such top having a plurality of holes, all of said holesbeing adapted to contain vessels to be heated from a single burner orfrom a number of burners less than the'total number of holes.

In the embodiment of my invention illustrated in the drawings I haveshown a fourhole gas-stove, all of the openings in the top thereof beingadapted to receive their heat from a single burner, said burner beingshown in dotted lines in Fig. land indicated by the numeral 3.

The holes are indicated by the numerals 4, 5, 6, and 7 respectively, thehole numbered 4 being immediately above the burner 3. The top of thestove shown in the drawings is divided by vertical walls into thecompartments 8, 9, 10, and 11, the walls being indicated by the numerals12, 13, 14, and 15. The wall 15 is imperforate, while the walls 12, 13,and 14 are provided with perforated dampers 16, 17, and 18.

The heat arising from the burner 3-is utilized primarily to heat thevessel placed over the hole 4:. The surplus heat and other products ofcombustion then find egress to the compartment 9 through the opening inthe wall 12, the passage of the heat and other products of combustionbeing controlled by the damper 16, which is actuated by the knob 19 orin any other suitable manner. The heat thus entering the compartment 9is utilized to heat a vessel or vessels placed upon the hole 5. The heatand other products of combustion are then admitted to the comparttheirpassage being controlled by the damper 17. The heat thus admitted to thecompartment 10 is utilized to heat vessels placed over the hole 6. Theheat and other products of combustion are then admitted to thecompartment 11 through the opening in the wall 1 1 to heat vesselsplaced upon the hole 11, the products of combustion finally findingegress from the stove through the flue-opening 20.

It is obvious that the gas-stove of my invention may be of any desiredsize and provided with any desired number of holes and that theheat-supply may be reinforced at any desired point during thecirculation of the heat-current beneath the holes. Thus if a high degreeof heat were desired in the compartments 10 and 11 an additional burnercould be inserted in the compartment 10, and

upon the same principle any desired degree of heat might be maintainedin any desired number of compartments.

In order to assist in the conservation of heat generated by the burner3, the outer sides, tops, and bottoms of the compartments 8, 9,

10, and 11 are provided with a lining of non-' conducting material,(indicated by the nu- Ineral 21,) which may be constructed from asbestosor any other desired substance. The compartments 9, 10, and 11, whichare not occupied .by burners, may be utilized as warming-closets or maybe provided with watercoils for the further utilization of the heat, ifdesired.

Having thus described my invention, what I claim as new, and desire tohave secured to me by the grant of Letters Patent, is

A gas-stove comprising, an imperi'orate bottom; imperi'orate wallsextending upwardly around the edge of said bottom and forming aheat-chamber; partition-Walls dividing said heat-chamber intoheat-compartments; there being passages through said partitions toconnect said heat-compartments in series; valves for controlling saidpassages; a top closing said heat-compartments, there being an openingin said top for eachheat-compartment to receive cooking utensils; and aburner in the first heat com partment of the series; there being meansof leading the products of combustion from the last heat-compartment ofthe series.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
